The 2nd workshop of air shower detection at high altitudes

In the last two years after The First Workshop for Air Shower Detection at High Altitudes, Pingshan, China, 2009, the ARGO-YBJ experiment has been publishing exciting observational results, the HAWC water tank array and Muon Detectors in the ASg array have been under construction and the LHAASO project has been significantly pushed forward. It is a moment for having the second workshop for all interested to update the progresses in the experiments, projects and corresponding prototypes, discuss physics and designs for the new projects and seek collaborations between groups, etc. We are going to hold The Second Workshop for Air Shower Detection at High Altitudes in the Institute of High Energy Physics (IHEP), Beijing, on February 17th -19th, 2011.
